their first Stanley Cup championship since 1961, the game-winning puck is still missing.

The rubber disc hasn't been found since it was dug out of the net while the Blackhawks celebrated their victory over the

Philadelphia Flyers

at the other end of the ice. An auction house says the collectible is worth six figures, at least, and a Chicago sports collector is offering a $50,000 reward for its return.

Images from the game showed veteran linesman Steve Miller looking at the puck in the moments after Kane's goal, but he has denied that he touched it.

However, the Tribune last week located a series of photos by a staff photographer that clearly show Miller picking up the puck with his right hand, shifting it to his left and skating away.

When the Tribune presented the pictures to Miller in Boston, where he is officiating the

Stanley Cup Final

between the

Bruins

and the

Canucks

, Miller he said he didn't remember picking up the puck and doesn't know where it is.

"I pick up a thousand pucks a year," Miller told the Tribune. "You can ask me what I did with a puck 10 minutes ago. I can't remember every single thing I do with a puck."

In the mystery of the missing puck, the photos provide a clue — but they haven't solved the case.

Gary Meagher, the

NHL

's senior vice president for communications, said the league spoke with Miller about the incident several months ago and stands by the linesman's account.

"He didn't remember getting the puck," Meagher said in Boston. "We sat with him. We met with him. I've talked to him numerous times. Other league officials have talked to him.

"We all wish we knew where the puck was."

The Hawks do too.

"I would certainly like to see the Blackhawks be in possession of that," team President John McDonough told the Tribune. "If ... someone would deliver it to the Blackhawks, it would be very meaningful."

Bill Hay

, a member of the Hawks' 1961 Stanley Cup team, said the puck belongs in the Hockey Hall of Fame, of which he is chairman and CEO. "Those pucks should go on display and not on

eBay

for someone to make money off of," Hay said. "It's important to the Hall of Fame and to the public."

The NHL's officiating handbook does not address what is to happen to pucks once games end, and no rule prohibits a hockey official from taking one. Miller said there were several things he may have done with the puck — throw it in a bucket with others, for example. But he told the Tribune he can't recall.

Andy Van Hellemond, a Hall of Fame referee living in Canada, said it is not uncommon for referees to snag pucks and that he's got "quite a few" in his collection, including ones shot by

Mario Lemieux

and Johnny Bucyk. The motivation, according to Van Hellemond: If a player reaches 500 goals in a career, wouldn't it be "neat" to have the milestone puck?

And what of Miller, the last person seen with the puck from Kane's goal?

"He's the only one who can unconfuse you," Van Hellemond said.

Miller, 38, has been an NHL linesman since 2000 and began working playoff games his second season. He lives with his family in a small Ontario city where he played junior hockey for the Stratford Cullitons.

Last June, he was one of four officials (and one of two linesmen) working Game 6 of the series between Philadelphia and Chicago.

. The puck became stuck in the netting, out of sight of players, fans and officials. The red light signifying a goal never came on, and the shot was a ruled a score only after video review.

Miller told the Tribune he remembers going to see whether the puck was in the net. "We have to know whether it was a goal or not," he said. "And nobody knew if it was a goal."

Miller said he doesn't remember what happened after the puck was dislodged except that the Hawks were at the other end of the ice, swarming goalie

In the previously unpublished Tribune photos, Miller is seen retrieving the puck from the goal, then holding the puck in his right hand as he settles the displaced goal back on its moorings. Miller then skates away from the goal with the puck in his left hand.

took the photos with a camera mounted behind the net that was activated remotely from his position elsewhere in the stadium. A wider search of the Tribune's photo archive, which contains tens of millions of images, turned up the photos last week.

Since that June night in Philadelphia, what happened to the puck has been a cause for great debate and many conspiracy theories. For Chicago, which lives and often dies with its teams, a missing Stanley Cup-winning puck matters.

A Chicago police sergeant offered amateur video, taken from his seat in Philadelphia, that seemed to capture Miller picking up the puck. Grant DePorter, CEO of

Harry Caray

's Restaurant Group and the city's most prominent sports memorabilia collector, is offering a $50,000 reward.

"Chicago is being robbed of a treasure," DePorter said.

The clamor is such that DePorter has been aided in his search by

FBI

agents who have donated their time in the quest to solve the mystery by ruling out potential Cup-winning pucks using state-of-the-art photographic technology.

Pucks used by the NHL aren't numbered for identification, but the FBI is reasonably confident it could authenticate the puck shot by Kane if someone claims to have it, spokesman Ross Rice said. The bureau could subject it to microscopic tests, for example.

For his part, Kane said he's aware of various rumors: that former teammate

Ben Eager

took it, that current Hawks forward

Patrick Sharp

has it — or that a linesman grabbed it.

Kane remembers the chaos on the ice and regrets that no one from the Hawks thought to grab the puck for safekeeping. "You're thinking about going to lift the Cup," Kane said.

"It would be nice to bring it back to Chicago, where it belongs," he added. "Right now we're probably just hoping that it's not lost."

As the days pass, the puck's importance and potential worth are only increasing. It currently could fetch at least $100,000, said Michael Heffner, president of the international auction house Lelands.

"As we speak, the legend of this puck grows," he said. "As the legend becomes larger, so does the value."

In April, ESPN.com wrote about showing Miller an Associated Press photo in which the linesman appears to be looking at the puck resting on the ice.

ESPN

did not have photos showing Miller with the puck in his possession.

"I never touched it," Miller was quoted as saying. In the interview, he repeated that denial several times.

As the controversy picked up steam, including after an April broadcast on the Canadian

television network

CBC that appeared to show Miller picking up the puck, Miller was removed by the NHL from this year's playoffs. But he was reinstated for the Stanley Cup Final series and was on the ice for Game 3 Monday.

Meagher said the league decided to sit the linesman during the playoffs not as punishment but to avoid attention. "We agreed for a period of about a week or 10 days that we didn't want the distraction in the playoffs," Meagher said this week. "And (Miller) didn't want it."

Terry Gregson, the NHL's senior vice president and director of officiating, said his department had looked into the matter and couldn't find the puck. He added that, in a change from previous years, officials working the playoffs "are not going near the pucks at the end of games. It is up to the team desiring it to retrieve it."

"From Steve's standpoint, he has found this personally very difficult," Meagher said. "As a guy of integrity, he doesn't want this to just continually be out there. I know people have wanted to speak to him, and at the appropriate time after the playoffs we'll ask him if he wants to just sit and answer these questions."

Miller said he understands the significance of the puck to Chicago and the Hawks. He just wants the questions to go away.

"I'm just moving on from this," Miller told the Tribune as he headed for his Boston hotel room. "The best thing to do is move on from this situation."
